Albuca leaves

Dear Mary Sue
Your photo listed as Albuca spiralis probably is this species, but you'll
still need flowers to confirm the genus. Also, your species 3 might be A.
flaccida; you'l definitely need the key from The Color Encyclopedia of Cape
Bulbs to verify this.
The other photos are definitely not Albuca. It is a species of Ornithogalum
subgenus Osmyne (as it is currently classified - may be changed to genus
Coilonox). The flowers of this group of species are even less variable than
in the very closely related Albuca; the species are mainly distinguished by
their leaves, which often are also quite interesting.
